The top shooting group and the side shooting group are connected to the computer to upload the pictures for calculation, and the number of IC chips and abnormal points on the tray are output by picture comparison, so as to achieve the purpose of automatic counting, which can largely avoid human errors, reduce human workload and operation difficulty, and further improve the degree of work standardization and automation. (2) The present invention installs a fill light group on the top of the counting area, and uses the fill light group to irradiate fill light on the tray, thereby improving the clarity of the photos taken by the shooting group. At the same time, by designing the fill light group into a structure in which a light panel, a lamp holder, a fill light and a driving component cooperate with each other, it is convenient to adjust the fill light position of the fill light through the driving component 2 during use, so as to meet the purpose of clear photography of trays of different models.

[0032] (3) The present invention installs a movable frame on the inventory area, and installs the side shooting group through the movable frame. When it is necessary to shoot through the side shooting group, the height can be adjusted by cooperating with the movable frame and the driving member. At the same time, the movable frame is designed to have a structure in which a lifting frame, an angle frame and a driving member cooperate with each other. When it is convenient to use, the angle between the lifting frame and the angle frame can be changed by the driving member three, thereby changing the shooting angle of the side shooting group, which is easy to meet different usage requirements.

S3: When counting is required during the processing, you only need to identify the corresponding Tray model to automatically adjust the fill light to the best fill light position, and then use the top shooting group to shoot the Tray. The photos taken are compared with the learning sample pictures, and the number of IC chips with or without IC chips is determined based on the different reflections of IC chips (implemented through the image comparison module). S4: When the top shooting group cannot clearly determine the IC chip in the Tray, the side shooting group can be started to assist in shooting.
